That would b great. Ill def pop around this weekend as im very busy untill saturday afternoon.
Great as u r just arount the corner from me
Is urs exactly the same?

I think the speed converters quite often throw up a speed sensor fault on the ECU. Also I suspect that cutting the speed limiter wire does the same. Neither of which are actually an issue.
ECU seems to be a good place to look if the relay, fuse and pump are all okay.
I still think it is the relay but you can try mine when you come over.

I wish it was relay, but i bypassed ECU and send +12V from battery straight to the relay and it clicks and pump kicks in so
telay is fine.
Speed sensor fault sorted, that was that loose connection on the converter.
Big thanks to DeK for lending me his AYC ECU. Put it on my car and still no difference, AYC still not working.
Check the wiring harness from the ECU to the pump relay - it could be a loose or cut wire, or a loose connector.
My relay did exactly the same. I checked it out on the bench, it clicked,the circuit was activated and it seemed fine but when, after many other abortive checks on the AYC system, I finally swopped it for another it showed that for some reason in situ it did not function so please, just for my peace of mind, try another before you go to the expensive remedy.
Yeah will do it.
I may try to get brand new one.
Again, you are welcome to try mine at least I know it works.
Big thanks to John, put his relay on my car and still doesn't work.
Took differente root back home and put big smile on my face decat pipe was very well spend money
Update.
Vehicle speed sensor fault is back.
As i was working on the car last night, managed to take speed sensor of the car just for the visual check up.
Once i had it on the bench i tested resistance between each combination of 2 pins out of 3 on the speed sensor, all the results were 0 ohm,
is that correct for fully working vehicle speed sensor?
There may be a testing procedure in the service manuals, indicating readings expected between pins.
the manuals will be on the club in the library somewhere but they are available online on a Russian website.
I'd still be pointing my finger at the wiring or connectors - there could be a small cut in the sheathing of one of the wires which has let some water in.
If you get the car off the ground and put it in gear, then turn the wheel - do you get a voltage reading at the relay and pump?
Very strange. We had 2 nice warm suny days, didnt drive yesday but drove it today and AYC was working.
I think i have to move to Spain or Italy
Finally managed to sort out the problem with my AYC.
Due to lack of arch liners, slightly too big wheels (235/40 R18) and far too much lowered suspension by previous owners 3 wires been ruubed through above front left wheel
( ABS sensor wires and pump relay signal ). Previously repaired one of the wires by somebody but very poorly so as soon as water got there AYC was failling and ECU was throwing out code 81 pump relay.
All wrapped up properly and AYC is working in the rain too.
Happy days cause i was going to blame the pump or switch and start with fitting new switch.
